SPECIFICATION forming part of Letters Patent No. 418,344, dated December 31, 1889.

Application filed December 3, 1887. Renewed October 17, 1889. Serial No. 327,290, (No model- To all whom it may concern; by dotted lines in Figs. 4 and 7,) the bar Be it known that we, ALBERT \VHITE and being secured thereto by a pin E, driven hor1- GEORGE l). DUDLEY, both citizens of the zontally into or through said bar, and the United States, residing at Lowell, in the pivot D, said pivot-pin D passing vertically 5 county of Middlesex and Commonwealth of through the handle A and down into or Massachusetts, have invented a certain new through the bar (l and being provided wit and useful Improvement in .llate-Lifters, of a head (1 above said handle. The head dof which the following is a specification. the pivot-pin D not only prevents the pin I) Our invention relates to plate-lifters, and from being drawn down through the handle to has for its object to enable a plate or dish to A, but is of a proper shape to serve as a pmbe turned readily in an oven without removion, it being provided with teeth (1 to ening the plate and its contents from the oven, gage the teeth 1" of the rack-bar F, which also serving the usual purpose of a plate slides upon the top of the handle A, and te which, being given a longitudinal motion, I5 In the accompanying drawings, Figure 1 is causes the pin D and the bar 0 to turn. The an isometric view of a plate-lifter provided teeth of the pinion are one more in number with our improvement and a plate held by than the teeth of the rack, and oceupysuch said lifter; Fig. 2, a plan of said lifter holda portion of the periphery of the pinion ing a plate; Fig. 3, an enlarged plan of a (the part (1 of the pinion being without teeth) 20 part of the handle of the lifter and of the as will enable the bar C to turn end for end, rack-bar and segmental pinion, the swivelor through an arc of one hundred and eighty iug bar and its stops being shown in dotted degrees, until a tooth of the pinion strikes lines; Fig. 4, a side elevation of a part of the against the untoothed part of the rack-bar F handle, part of the rack-bar, the swiveling and prevents a further rotation of the pinion 25 bar, the pinion, and the upper part of the (Z and bar 0.

lifting-jaws, showing the jaws hinged to said The rack-bar F (which is preferably a wire bar; Fig.5, an elevation of that end of the bent to form the teeth f) is guided by staples lifter which is at the right in the other fig- G, which secure it to the handle,but allow it ures, the lower part of the jaws being broken to slide thereon freely. The end of the rack- 0 away; Fig. 6, a plan of part of the handle, bar nearest the pinion is bent transversely the rack, and the pinion, the pinion being past the pinion and down over the side of the turned one hundred and eighty degrees from handle at f and into the longitudinal groove the position it occupies in Fig. 3; Fig. 7, a a in said side of said handle to hold the rack side elevation of our improved lifter applied in engagement with the pinion laterally and 3 5 to a plate. to prevent the rack-bar from rising away from The handle A is a straight bar, preferably the handle A. The end of the rack-bar farof wood. The swinging jaws B are of the thest from the pinion is bent into aloop f at customary form shown, but, instead of being about right angles to the general direction of hinged directly to the handle, are hinged to said rack-bar to form a thumb-rest against 9 40 the swiveling bar C, the upper ends of each which the thumb of the hand which grasps jaw being bent toward each other into hooks the handle may be drawn or pushed to slide 1) and entering eyes secured to or staples c the rack-bar, and thereby to turn the bar 0, driven into opposite sides of the bar 0 near and with it the jaws B and the plate held in its ends, and enabling either jaw to be raised said jaws. 45 laterally by turning the handle A or bar 0 To prevent the bar 0 from turning more on its longitudinal axis against such jaw to than half-way around on its pivot, one arm separate the jaws and to allow them to be en- 0 of said bar is slightly longer than the other,

gaged with a plate in the usual manner. The the two stapleswhich support either jaw bejaws B are both alike, and the sides of the ingat the same distance from the center of mo- I00 50 bar 0 are both alike. The bar 0 is pivoted tion of said bar, and the handleA is provided to the handle A by a vertical pin D, (shown with two stops a 02 which project downward from said handle near the edge of the same on the same side oi the longitudinal axis oi said handle, (which is somewhat wider than said bar,) the distance of the stops re from the center of motion of said bar being greaterthan the length of the short arm of said bar and less than the length of the arm so that said arm e will. strike said stops at u alternately as said bar is swiveled. 'lhese steps may be simply wire staples driven into the handle, as shown in Fig. 4'.

It is well-known that pies and other articles of food baked in dishes or plates are frequently baked faster on one side than on the other, and require to be partly turned around to expose the least-baked portion to the hotter side of the oven. By the use of the abovedescribed lifter a plate may be lifted slightly from the bottom of the oven and turned halfway or less around, even when the plate to be moved is behind other plates, without moving any of said plates from the oven and without any danger of burning the hands or arms.

lhe lifter can be used to merely lift or move the plates in or from the even without turning them, the turning devices not being automatic.

e claim as our invention- 1. The combination of the handle, the swiveling bar, jaws swinging on said bar, a pin passing through said handle and secured to said bar, a pinion secured to said pin above said handle, and a rack-bar sliding on said handle and provided with teeth to engage said pinion, whereby a longitudinal movement of said rack-bar will cause said swiveling bar and said jaws to be turned, as and for the purpose specified.

2. The combination of the handle, the swiveling bar, jaws swinging on said bar, a pivotpin connected to said bar and turning in a hole with which said handle is provided, a pinion secured to the upper end of said pivotpin above said handle,and a rack-bararranged above said handle and sliding thereon, and guided by staples embracing said rack-bar and driven into said handle, and provided with teeth to engage said pinion, and having a thumb-rest adapted to be drawn or pushed by the thumb of the hand gras iing said handle to impart a longitudinal motion to said l't\( l( l)tl', and thereby to rotate said swiveling bar and said jaws, as and for the purpose specified.

13. 'lhccombination ol' thehandle,theswiw eling bar, apivot-pin secured to said swiveling bar and extending upward through a hole with which said handle is provided, and a pinion secured to said pivot-pin concentrically therewith above said handle and sliding thereon. and provided with teeth to engage said pinion, said rack-bar having one tooth less than said pinion, whereby when said pinion is retated by the longitudinal movement of said raclebar a tooth of said pinion comes in contact with the untoothed portion of said rackbar and limits the motion of said rack-bar and said pinion, as and for the purpose specified.

at. The combination of the handle, the swiveling bar, the jaws swinging from said bar, a

pivot-pin passing through said handle and turning freely therein and secured to said bar, a pinion secured to said pin above said handle, the rack-bar formed of wire, for a portion of its length bent into teeth adapted to engage the teeth of said pinion, and having one of its ends bent transversely past said pinion and over the side of said handle and into a longitudinal groove with which the side of said handle is provided, and having its other end bent into a thumb-rest adapted to be drawn or pushed by the thumb of the hand which grasps said handle to impart longitudinal motion to said rack-bar, and staples embracing said rack-bar and driven into said handle, whereby said rack-bar is guided and its teeth are kept in engagement with said pinion to rotate said swiveling bar and said jaws, as and for the purpose specified.

In witness whereof we have signed this specification, in the presence of two subscribing witnesses, this 30th day of November, A. D. 1887.
